Answer
Hypothalamus
Explanation
The 'Hypothalamus' acts as the body's internal thermostat. Located at the base of the brain, it regulates body temperature, hunger, thirst, sleep cycles, and emotional responses. When the body temperature rises, the hypothalamus triggers sweating to cool the body down, and when it drops, it triggers shivering to generate heat.
Key Points
- > Hypothalamus regulates body temperature (thermoregulation).
- > It connects the nervous system to the endocrine system via the pituitary gland.
- > Cerebrum is responsible for intelligence, memory, reasoning, and voluntary actions.
- > Cerebellum maintains body posture and balance.
- > Medulla Oblongata controls involuntary vital functions like heartbeat and respiration.
